The current development kernel is 2.5.40
by Linus on October 1. Among the
usual fixes and updates, it includes high memory support for User-mode
Linux, the CPU frequency (power management) patches, more disk management
thrashups from Al Viro, the in-kernel NUMA topology API, the removal of the
task queue subsystem, an ISDN update, and an ARM update. Here's the long-format changelog
with the details.
Linus announced 2.5.39 on
September 27. The biggest change,
perhaps, was the inclusion of the deadline I/O scheduler (covered in last week's LWN Kernel Page);
this kernel also contained a bunch of XFS fixes, an SCTP update, a bunch of
memory management work by Andrew Morton, Ingo Molnar's in-kernel symbolic
oops dumper, some driver model work, and numerous other fixes and updates.
long-format changelog is available.
Linus's pre-2.5.41 BitKeeper tree contains a big ALSA update (the source of
some grumbling from Linus), Ingo Molnar's
"workqueue" implementation (see below), and a relatively small number (as
of this writing) of other fixes and updates.
Dave Jones jumped back into the prepatch business with 2.5.39-dj1, which contained a number of fixes
from his tree. Dave evidently still has a substantial pile of fixes to
push on to Linus, but has been busy.
After a long absence, Alan Cox has also started putting out development
kernel prepatches again. 2.5.40-ac1
includes support for the Voyager architecture, a merge of the uClinux
distribution, and a number of fixes.
The latest 2.5 status summary from Guillaume
Boissiere is dated October 2.
The current stable kernel is 2.4.19. Marcelo released 2.4.20-pre8 seconds after last week's Kernel
Page was posted; it included an IBM hotplug driver update, a couple
of security fixes, an x86-64 update, and a number of other fixes.
The current prepatch from Alan Cox is 2.4.20-pre8-ac3. Alan's recent releases have
contained quite a few fixes, but no major new work.
